About Us

Stonewood Builders is happy to build your new home, remodel or add on to your existing home, in areas of Wisconsin. We mainly concentrate on the areas around Dane County including Madison, Middleton, Sun Prairie, Cottage Grove, Fitchburg, Stoughton, DeForest, Oregon, Verona, Waunakee, McFarland, Cross Plains, Mt. Horeb, and all other surrounding communities.

Being a custom builder, each home and it’s pricing is different due to design. No two homes we build are alike. While that means each client has a custom home, it also means no two home are the same price. When pricing a home for a client, we find out the “must haves” and what is on the “wish list.” This creates a base price for that specific home and then provides a client the opportunity to see the pricing of options. Clients may choose one, a few or all of the additional options. All these choices affect the cost per square foot.
